| 20080278814 | STRUCTURED SURFACE ARTICLES CONTAINING GEOMETRIC STRUCTURES WITH COMPOUND FACES AND METHODS FOR MAKING SAME - A prepared substrate including an array of cube corner cavities and protrusions interspersed between the cube corner cavities is described herein. | 11-13-2008 |
| 20090169823 | CUBE CORNER CAVITY BASED RETROREFLECTORS WITH TRANSPARENT FILL MATERIAL - Retroreflective sheeting includes a body layer having a structured surface with recessed faces forming cube corner cavities. A reflective film is disposed at least on the recessed faces, and a fill material fills the cube corner cavities. The fill material comprises radiation-curable materials, adhesives, or both, and preferably transparent radiation-curable pressure-sensitive adhesives. The fill material preferably forms a continuous layer covering both the recessed faces and upper portions of the structured surface. A transparent cover layer preferably contacts the fill material layer. | 07-02-2009 |
| 20090185272 | METHOD OF MAKING RETROREFLECTIVE SHEETING AND ARTICLES - The invention relates to a method of making retroreflective sheeting and other articles prepared from casting a moldable synthetic resin onto a tool having a microstructured surface. | 07-23-2009 |
| 20090257124 | LAMINA COMPRISING CUBE CORNER ELEMENTS AND RETROREFLECTIVE SHEETING - The present disclosure is directed to lamina(e) comprising cube corner elements, a tool comprising an assembly of laminae and replicas thereof. The disclosure further relates to retroreflective sheeting. | 10-15-2009 |
| 20100103521 | RETROREFLECTIVE SHEETING - The present application relates generally to retroreflective sheeting and the tools and methods used to make retroreflective sheeting. Microreplication tools and sheeting include controlled surface structure or haze. The surface structure or haze can be introduced, for example, by chemical etching of the tool surface and/or electroplating. | 04-29-2010 |
| 20100182695 | STRUCTURED SURFACE ARTICLES CONTAINING GEOMETRIC STRUCTURES WITH COMPOUND FACES AND METHODS FOR MAKING SAME - A prepared substrate including an array of cube corner cavities and protrusions interspersed between the cube corner cavities is described herein. | 07-22-2010 |
| 20100226009 | METHOD OF MAKING RETROREFLECTIVE SHEETING AND ARTICLES - The invention relates to a method of making retroreflective sheeting and other articles prepared from casting a moldable synthetic resin onto a tool having a microstructured surface. | 09-09-2010 |
| 20100232019 | LAMINA COMPRISING CUBE CORNER ELEMENTS AND RETROREFLECTIVE SHEETING - The present disclosure is directed to lamina(e) comprising cube corner elements, a tool comprising an assembly of laminae and replicas thereof. The disclosure further relates to retroreflective sheeting. | 09-16-2010 |
| 20100265584 | RETROREFLECTING OPTICAL CONSTRUCTION - Retroreflecting optical constructions are disclosed. A disclosed retroreflecting optical construction includes a retroreflecting layer that has a retroreflecting structured major surface, and an optical film that is disposed on the retroreflecting structured major surface of the retroreflecting layer. The optical film has an optical haze that is not less than about 30%. Substantial portions of each two neighboring major surfaces in the retroreflecting optical construction are in physical contact with each other. | 10-21-2010 |
| 20110149395 | COMPOUND MOLD AND STRUCTURED SURFACE ARTICLES CONTAINING GEOMETRIC STRUCTURES WITH COMPOUND FACES AND METHOD OF MAKING SAME - Structured surface articles such as molds or sheeting are formed on a compound substrate including a machined substrate and a replicated substrate. In one embodiment, the structured surface is a cube corner element on a compound substrate. In another embodiment, the structured surface is a geometric structure that has a plurality of faces, where one face is located on the machined substrate and another face is located on the replicated substrate. In yet another embodiment, at least some of the faces include a compound face with a portion formed on the machined substrate and a portion formed on the replicated substrate. The method of making a structured surface article including a geometric structure having a plurality of faces includes forming an array of geometric structures in a first surface of a machined substrate; passivating selected locations of the first surface of the machined substrate; forming a replicated substrate of the machined substrate to form a compound substrate; forming an array of second geometric structures on a second surface opposite the first surface on the machined substrate; and removing selected portions from the second surface of the machined substrate. | 06-23-2011 |
