| 摘要 |
A radiation-polymerisable mixture which contains a) a compound polymerisable by a free-radical mechanism and having a boiling point above 100 DEG C, b) a photoinitiator and c) a copolymer with units of c1) an alpha , beta -unsaturated aliphatic carboxylic acid, c2) an alkyl, cycloalkyl or cycloalkenyl methacrylate and c3) an alkyl, cycloalkyl or cycloalkenyl acrylate and has an acid number from 78 to 176 and a glass temperature from 290 to 340 K, is distinguished by easy developability at low acid number and good resistance to alkaline etching solutions. |
