Abstract

A pressure sensitive recording developer sheet comprising a phenolic resin developer coating on a support, the improvement which comprises said phenolic resin developer being a resin which is obtained by modifying with an alkylphenol compound represented by the general formula WHEREIN R1+L, R2 and R3 which may be the same or different each represents a hydrogen atom or an alkyl group with the proviso that they simultaneously should not be hydrogen atoms, in the condensation of p-phenyl phenol and aldehyde. The coating may also contain microcapsules containing a substantially colorless coupler. [US3857721A]
