I. Applications of long persistence phosphor in paint and printing ink as a pigment.
Long persistence phosphor can be mixed with various transparent resins, such as acrylic acid resin, polyurethane, epoxy, amino, polyvinyl butyral, and polyamide resin, becoming luminous paint and printing ink. The recommended percentage of long persistence phosphor in paint is about 10 - 50%, however, 30 - 60% in printing ink. First, these resins should be dissolved with some appropriate solvents into a solution, then long persistence phosphor will be added into the solution. Some anti-precipitating agents, ridding foaming agents and dispersing agents also need to be added into the solution, well mixed into a uniform solution by using a high speed mixer. However it must be avoided to grind them with mechanic abrader in order to keep the property of the pigment. In the case to use sand abrader becomes necessary, the grinding time should be as short as possible.

III. Applications of the Long persistence phosphor in luminous plastic granule for plastic molding
The long persistence phosphor can be mixed with various resins such as PE, PP, ABS, and PVS, becoming luminous plastic granule. Using these plastic granule, a variety of plastic products can be made by extrusion, injection molding, blowing and vacuum molding. Mixing with some appropriate auxiliaries and resins, they can also be made into luminous films and artificial leather. The quantity of the long persistence phosphor used can be in a range of 20 - 50 wt% of total weight, based on different applications. The plastic life span will not be affected by adding the pigment. However, please do not add any lead auxiliary into the mixture or operate in copper molds while making the final plastic. Otherwise the brightness of the plastic products will be damaged.
