ABSTRACT:
A developer sheet comprising a support having a layer of a color developer on the surface thereof, said color developer being capable of reacting with a substantially colorless electron donating color former to produce a color image and being an acrylic or methacrylic polymer having pendant developer moieties (e.g., hydroxy aromatic or aromatic acid moieties such as salicyclic or phthalic acid moieties) which are preferably metallated (e.g., zincated) or being the polymeric reaction product of vinyl salicylic acid or salt.
