Abstract
A fluorescent and/or phosphorescent coating composition, particularly useful as a body coating, hair coating, lipstick and particularly as a phosphorescent nail polish that has the capability of changing from transparent, or other color, in light to a phosphorescing or fluorescing composition upon the withdrawal of light. The composition, e.g., nail polish, will return to its original color, as originally perceived by a human eye, as soon as light again contacts and is absorbed by the phosphorescent or fluorescent composition. The nail polish of the present invention is capable of undergoing a reversible chemical change upon the withdrawal of light without altering its physical properties.
Claims18
A light-emitting coating composition for coating a human body part comprising a solvent;
- an emulsifying agent capable of dispersing a phosphorescent material in the coating composition;
- a film-forming resin capable of forming a continuous film upon solvent evaporation;
- an effective amount of an anti-settling agent;
- and a light-absorbing phosphorescent material in an amount sufficient to emit a visible amount of light after being contacted by light and then removing light from contacting said light-absorbing material.
A method of coating a human body part such that said coated body part emits visible light after said coated body part is contacted by light and then said body part is disposed in a dark environment, comprising coating said body part with a composition comprising a solvent;
- a film-forming resin capable of forming a continuous film upon solvent evaporation;
- an effective amount of an anti-settling agent;
- a light-absorbing phosphorescent material dispersed in the composition;
- and evaporating the solvent to form a continuous film on said body part.
A method of manufacturing a light-emitting coating composition for coating a human body part comprising:
- mixing a solvent, an emulsifying agent and a film-forming resin to form a homogenous dispersion;
- adding a phosphorescent pigment to the homogeneous dispersion and mixing for a time sufficient to fully disperse the phosphorescent pigment;
- adding an anti-settling agent in an amount sufficient to prevent settling of the phosphorescent pigment, mixing initially at an impeller speed less than 1000 rpm, and then increasing the impeller speed to a speed not to exceed 3000 rpm.
A method of coating a human body part such that said coated body part emits visible light after said body part is contacted by light and then said body part is disposed in a dark environment, comprising coating said body part with a composition comprising a solvent;
- a film-forming resin capable of forming a continuous film upon solvent evaporation;
- an effective amount of an anti-settling agent;
- and a compound that is capable of absorbing light and then capable of emitting light when exposed to a dark environment, said compound dispersed in the composition;
- and evaporating the solvent to form a continuous film on said body part.
