20100062357 | Pigment Preparation Based on Diketopyrrolopyrroles - The invention relates to a pigment preparation based on C.I. Pigment Red 254 content with an average particle size of between 20 and 100 nm, and to at least one pigment dispersant of formula (II). | 03-11-2010 |
20100221654 | Pigment Preparations Based on C.I. Pigment Blue 15,6 - The invention relates to novel fine-particle pigment preparations comprising fine-particle C.I. Pigment Blue 15:6 as a base pigment and pigment dispersants of formula (II) wherein CPC is a radical of a copper phthalocyanine, n is a number between 0.1 and 4, preferably between 0.2 and 2; m is number between 0.1 and 4, preferably 0.2 and 2; Kat is a cation from the group of alkali metals or H | 09-02-2010 |
20110012072 | Use of Hydrophobic Solvent-Based Pigment Preparations in Electronic Displays - The invention relates to the use of a pigment preparation as a dye for producing a colored optical image in an electronic display, said pigment preparation containing (A) at least one organic and/or inorganic pigment, (B) at least one solvent-soluble or solvent-dispersible polymeric dispersant, (C) at least one aldehyde resin or ketone resin, (D) optionally further additives common for producing solvent-containing pigment preparations, and (E) at least one hydrophobic solvent. | 01-20-2011 |
20110041913 | Use of Hydrophobic Solvent-Based Pigment Preparations in Electronic Displays - The invention relates polysilazane-containing coatings for increasing the light permeability of sun-facing covers of solar cells. The coating for surfaces contains at least one polysilazane of formula (1) —(SiRR′R″—NR′″1)n— (1), wherein R′,R″,R′″ are the same or different or represent an optionally substituted alkyl, aryl, vinyl or (trialkoxysilyl)alkyl group, n being an integer and n being chosen in such a manner that the perhydropolysilazane has a number average molecular weight of 150 to 150,000 g/mol, a solvent and a catalyst. The cured coating has a thickness of at least 0.50-10 micrometer, preferably 0.2 to 5 micrometer, especially preferred 0.5 to 1.5 micrometer. It is especially suitable as transmission-promoting coating for use in sun-facing covers of solar cells. | 02-24-2011 |
