Water developable photosensitive resin composition.

摘要

Disclosed is a water developable photosensitive resin composition suitable for a printing plate, which has excellent dimensional stability and excellent chemical and physical properties. The photosensitive resin composition comprises; (A) an acrylic resin of which glass transition temperature (Tg), as defined by $[wherein\; Tg1,\; Tg2,\; ....\; represents\; a\; glass\; transition\; temperature\; of\; a\; homopolymer\; prepared\; from\; each\; monomer,\; Tg0\; represents\; a\; glass\; transition\; temperature\; of\; a\; copolymer\; and\; W1,\; W2,\; ....\; shows\; a\; weight\; fraction\; of\; each\; monomer.]\; and\; acid\; value\; (AV)\; satisfy\; the\; following\; relations;\; 60\; DEG\; C$
