ABSTRACT:
Photopolymerizable composition comprising monomer, photoinitiator and triarylmethane or xanthene dye exhibit increased photospeed with an exposure to light above 400 nm with an intensity of at least 1500 lumen/sq. meter for one hour or more, with a preferred exposure of 15,000 lumen/sq. meter for 10 seconds or longer. A photospeed layer protected from exposure to oxygen has been shown to continue to maintain increased photospeed.
