ABSTRACT:
Formaldehyde-free resins of the formula (I): ##STR1## where n is an integer greater than or equal to 2, the phenolic units of the resin are directly bonded to one another through positions ortho or para to the hydroxyl group, Y is present at a position meta or para to the hydroxy group and is selected from the group consisting of an alkyl group, a halogen atom, an aryl group, a phenylalkyl group, an allyl group, a carboxyl group of the formula --COOR, where R is a hydrogen atom, an alkyl group or a phenylalkyl group, an amino group of the formula --NR.sub.1 R.sub.2 where R.sub.1 and R.sub.2 are the same or different and represent a hydrogen atom or an alkyl group, and Z is a hydrogen atom, an alkyl group, a halogen atom, an aryl group, a phenylalkyl group, or a --COOR group, or Z in conjunction with the adjacent meta position forms a condensed benzene ring; or a metal-modified, formaldehyde-free phenolic developer resin obtained by reacting said developer resin with a metal salt; the resins are useful as developers in forming colored images by reaction with substantially colorless electron-donating compounds.
