PURPOSE:To make it possible to display a scale, a pattern, a character, etc., without spoiling characteristics of a fluororesin coating by destroying or deforming microcapsules in the fluororesin coating contg. the microcapsules wherein a pigment is enclosed and thereby providing a color difference from that of undestroyed or underformed parts. CONSTITUTION:As a pigment enclosed in a microcapsule, either an inorg. or an org. pigment can be used. As the microcapsule to be used, any type of micro capsule such as a product the wall membrane of which is destroyed or deformed by the chang in pressure can be used. The microcapsules are destroyed or deformed by providing an outer energy to release the pigment and a color difference from undestroyed or undeformed parts is thereby provided to display a scale, a pattern, a character, etc. As the fluororesin, e.g. polytetrafluoroethylene copolymer, etc., are used. Besides the microcapsule, if necessary, a pigment, an adhesive auxiliary etc., are properly incorporated in the fluororesin to form a fluororesin coating. |
