Title:
COLOR DEVELOPER RESIN COMPOSITION, ITS EMULSION AND ITS PREPARING PROCESS
Document Type and Number:
WIPO Patent Application WO/2005/040242
Kind Code:
A1
Abstract:
This invention relates to a color developer resin composition, which comprises: (1) phonolic resin of formula I; and (2) graft-copolymerized blend, represented by formulas II and III, obtained from the reaction of phenolic resin with polyvalent metal-salt polymer of substituted aryl carboxylic acid. The invention also relates to a color developer resin emulsion containing such color developer resin composition, and a process for preparing the same. The color developer resin composition and its emulsion according to the invention are special resin color developing agents especially used for carbonless copy paper, which have the advantages of both high color developing speed at low temperature, vivid tinct, and deep developing chroma, excellent light-aging property of writing, high resistance to yellowing of coating upon storage in air and the like. Hitherto they are relative desired resin developers.
