ABSTRACT:
Disclosed is a recording material which comprises a normally colorless or palely colored dye precursor and a developer which causes the dye precursor to form color upon contact with the dye precursor, said developer being a copolymer of (A) a styrene monomer with (B) at least one monomer selected from the group consisting of a vinylsulfonic acid type monomer, a (meth)acrylic type phosphorous-containing monomer and a (meth)acrylic acid type monomer. This recording material is excellent in stability of color image portion and non-image portion.
