ABSTRACT:
A photocrosslinkable substantially linear polyester polymer having sensitivity to visible light is provided which contains at least 10 mole %, based on the entire polymer, of units derived from a phenylenebis(.alpha.-cyanobutadienecarboxylic acid) and has a reduced viscosity of at least 0.2 dl/g. A typical use of the polymer is in making printing plates.
