CONFIDENTIAL POSTCARD

摘要

PURPOSE:To provide a handy confidential postcard having excellent contamination resistance and concealability of recording information. CONSTITUTION:A confidential postcard is formed by integrating a polyolefin resin laminated layer 4 and an electron beam curable resin layer 5 between first and second self-color development type pressure sensitive recording sheets 3 and 8, and formed by partly printing desensitizing ink on a pressure sensitive recording layer 7 of the sheet and further printing a ground tint thereon. Or, a ground tint is printed with desensitizing ink containing colored dyeing pigment in such a manner that a ratio of mean particle sizes of microcapsules to be used for the first and second sheets is 1:(0.4-0.6) and a mean particle size of the first microcapsule is 6-10mum.
