Abstract
A record member comprising a developer composition comprising a zinc-modified addition product of a phenol and a diolefinic alkylated or alkenylated cyclic hydrocarbon is disclosed. These addition products are particularly useful as color developers for basic chromogenic material.
Claims12
A record member comprising a substrate and a color developer composition comprising a zinc-modified addition product prepared by a process comprising mixing together and heating an addition product of phenol and a diolefinic alkylated or alkenylated cyclic hydrocarbon, a zinc compound selected from the group consisting of zinc oxide and zinc carbonate, benzoic acid and a weak base.
A pressure-sensitive record unit comprising:
- (a) support sheet material;
- (b) mark-forming components, and a pressure-releasable liquid organic solvent for both said mark-forming components arranged in contiguous juxtaposition and supported by said sheet material;
- (c) at least one of the mark-forming components being maintained in isolation from other mark-forming component(s);
- (d) said mark-forming components comprising at least one basic chromogenic material and at least one zinc-modified addition product prepared by a process comprising mixing together and heating an addition product of phenol and a diolefinic alkylated or alkenylated cyclic hydrocarbon, a zinc compound selected from the group consisting of zinc oxide and zinc carbonate, benzoic acid and a weak base, which components, on pressure release of the liquid organic solvent, are brought into reactive contact.
