<p>PROBLEM TO BE SOLVED: To provide a luminous cream which applies on a contracting/expanding article by mixing a luminous phosphor with cream agent. SOLUTION: A luminous phosphor is mixed with cream agent composed of extremely thick emulsion so as to form luminous cream. Petroleum, aqueous solution such as fluoreselen, canary glass, solid such as platinum cyanide, and sulfide in alkali earth metals, etc., are used for this light storage phosphor. Organic and inorganic fluorescent pigment can be also used. This luminous cream is used for a contracting/expanding article such as a condom so that rubber films are prevented from closely sticking to each other in manufacturing or storing and the feeling of the physical disorder due to friction can be reduced in using. One which is lost its function and safety required for the cream and the one which reduces the light emission power by mixing are not adopted as the cream used for the condom.</p> |
