RADIATION-SENSITIVE, ETHYLENICALLY UNSATURATED, COPOLYMERIZABLE COMPOUNDS AND THEIR PREPARATION

摘要

The ethylenically unsaturated organic compounds are of the general formula (see above formula) where R is alkyl, aryl or a radical R1, and R1 is a radical (see above formula) where R2 to R6 are each H, alkyl, OH, Oalkyl, SH, Salkyl, halogen, N(alkyl)2 or N(alkyl)(aryl), and not less than one but not more than three of the radicals R2 to R6 are each a radical (see above formula) where X is alkylene or oxaalkylene, each of 2 to 10 carbon atoms, and Y is H or CH3. These compounds have particularly high photochemical reactivity in the medium-wavelength to relatively long-wavelength UV range.
