A sheet for recording installed in measuring instruments such as a tachograph and a taximeter in which printing can be carried out with a recording pen using no ink. A water-based hiding agent is prepared by mixing a suspension so made that polymer particles (8) including bubbles therein are dispersed in a water paint, and the hiding agent is coated on a colored sheet (2, 5) to form a hiding layer (6) thereon. Since the bubbles near the centers of the polymer particles (8) in the hiding layer (6) scatter incident rays, the hiding layer (6) has a high scattering power and an excellent brightness and hides a ground color completely. Since the hiding agent forming the hiding layer (6) is aqueous, there is no possibility of flashing and exploding in coating. <IMAGE> |
