Title:
SENSITIZED PHOTOPOLYMERIZING COMPOSITION AND ITS USAGE IN LITHOGRAPHY FORM PLATE
Document Type and Number:
Japanese Patent JP3647960
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To provide a lithography form plate suitable for two demands of high photospeed and excellent storage life.
SOLUTION: In a photopolymerization initiator system containing a spectral sensitizing agent, by which sensitization is carried out in an ultraviolet/visible region of a spectrum, and a polycarboxylic acid coinitiator, the polycarboxylic acid co-initiator includes an aromatic group part substituted by a hetero atom selected from nitrogen, oxygen, and sulfur, and also includes two carboxyl groups in which at least one carboxyl group is bound to a hetero atom. Using this photopolymerizing initiator system, a lithography form plate is formed.
