摘要

Jolly /A Roos Case 1-2 CONTRAST COLORANT FOR PHOTOPOLYMERIZABLE COMPOSITIONS Stable print-out dye systems are provided for photopolymerizable compositions, finding particular use as photoresists. The dye compositions comprise a triarylmethane leuco dye in combination with a high-boiling, relatively thermallyinsensitive polyhalo alicyclic compound having at least five bromines. The print-out dye system is incorporated with an addition polymerizable composition, a light-sensitive initiator, and minor amounts of other additives.
