Abstract
The compound: ##SPC1## Which can be reacted with dialkylamine to form a product compound having the formula ##SPC2## In which: PA1 A. R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, R.sub.6, R.sub.7, and R.sub.8 are independently selected from the group consisting of hydrogen, fluorine, chloride, bromine, and lower alkyl; ##EQU1## b. A is C. R.sub.9 is ##SPC3## ##SPC4## PA1 An alkylene group having 2-20 carbon atoms, a cycloalkylene group having 3-20 carbon atoms, a phenylene group, an alkaryl group having 7-10 carbon atoms, or an aralkyl group having 7-10 carbon atoms; and PA1 D. R.sub.10 and R.sub.11 are independently selected from a group consisting of hydrogen, lower alkyl, a cycloalkyl group having 3-10 carbon aboms, a phenyl group, an alkylaryl group having 7-10 carbon atoms, and an aralkyl group having 7-10 carbon atoms. The product compound can be admixed with a polythiol to form a composition which is useful for (a) preparing printing plates and (b) protective coatings
