Record sheet |
| abstract |
A record sheet comprising a base sheet and coated thereon a layer of a developer which produces a colored image upon reaction with a color former such as crystal violet lactone, said developer comprising (1) a metal compound of an aromatic carboxylic acid such as a reaction product of 2-hydroxy-1naphthoic acid and zinc chloride and (2) a metal salt such as copper sulfate or nickel sulfate. The developer has improved color developing ability and the colored image produced has increased resistance to light. |
