PURPOSE:To improve an adhesive property between a base material and a thermosensitive color forming layer and eliminate the tackiness of the color forming layer by forming a mat layer between the base material and the color forming layer by applying printing, coating, etc. CONSTITUTION:A mat agent is used which consists of a white pigment (for example, silica in approximately 1-10mu grain size), a binding agent, a solvent, etc. That is, said mat agent is applied on a plastic film (a base material) 1 by applying printing or coating and a mat layer 2 with approximately 1-10mu thickness is formed, while thermosensitive color forming ink containing leuco dyes and a phenolic compound (for example, bisphenol A) is applied on the layer 2 and a color forming layer 3 is made up while the ink is permeated to the mat layer 2 and a thermosensitive recording type plastic card is obtained. |
