| 20080248428 | Method for Producing Flexographic Printing Forms by Thermal Development - The invention relates to a method for producing flexographic printing forms by thermal development during which a flexographic printing element exposed in an image-like manner is developed by heating and removing the softened, non-polymerized portions of the relief-forming layer, whereby the flexographic printing element used contains a styrene butadiene block copolymer mixed with a softener, and the proportion of butadiene which is 1,2-coupled, ranges from 15 to 50% by weight of the block copolymer. | 10-09-2008 |
