Abstract
Disclosed is a light sensitive composition containing a compound represented by the following formula (1): formula (1) 1 wherein R1, R2 and R3 independently represent a hydrogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkenyl group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted heterocyclic group, provided that R1 and R2 may combine with each other to form a ring or R2 and R3 may combine with each other to form a ring.
Claims11
A light sensitive composition containing a compound represented by the following formula (1):
- 14
- wherein R1, R2 and R3 independently represent a hydrogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkenyl group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted heterocyclic group, provided that R1 and R2 may combine with each other to form a ring or R2 and R3 may combine with each other to form a ring.
A light sensitive planographic printing plate precursor comprising a support, and provided thereon, a photopolymerizable light sensitive layer comprising a light sensitive composition containing a compound represented by the following formula (1):
- 18
- wherein R1, R2 and R3 independently represent a hydrogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkenyl group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted heterocyclic group, provided that R1 and R2 may combine with each other to form a ring or R2 and R3 may combine with each other to form a ring.
An image formation method comprising the step of imagewise exposing a light sensitive planographic printing plate precursor to light with a wavelength of from 380 to 430 nm, the precursor comprising a support, and provided thereon, a photopolymerizable light sensitive layer comprising a light sensitive composition containing a compound represented by the following formula (1):
- 22
- wherein R1, R2 and R3 independently represent a hydrogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkenyl group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted heterocyclic group, provided that R1 and R2 may combine with each other to form a ring or R2 and R3 may combine with each other to form a ring.
