  • Patent number: 4612254
    Abstract: Novel metal-modified phenolic resins useful in the color developer part of a carbonless copy paper system are disclosed, as well as methods for preparing such resins. The metal-modified phenolic resins are reaction products of an aromatic carboxylic acid and a partial condensation reaction product (an oligomer) of a phenol and an aldehyde. The metal-containing compound is added either to the mixture of phenol and aldehyde in forming the oligomer or to the mixture of aromatic carboxylic acid and the oligomer. The color developer materials of the invention are coated on a paper substrate which forms a part of a pressure sensitive recording paper system. The color developer materials exhibit improved performance over prior art colored developer materials.
