Document Type and Number:
Japanese Patent JP2003523445
Kind Code:
A
Abstract:
Luminescent polymers are prepared from thermosetting unsaturated polyesters, suspending fillers and phosphorescent pigments and utilized to make gel coated articles and molded, cast and fiberglass reinforced plastic (FRP) articles. The luminescent polymers show bright and long-lasting photoluminescent afterglow, strong thermostimulation of afterglow by heat and electroluminescent properties. The preferred thermosetting unsaturated polyester resins are prepared by condensing mixtures of ethylenically unsaturated and aromatic dicarboxylic acids and anhydrides with dihydric alcohols and a polymerizable vinylidene monomer. Phthalic (orthophthalic) and isophthalic aromatic modified polyesters and their substituted derivatives are preferred, particularly those formed from maleate or fumarate unsaturated dicarboxylic acids and anhydrides and a glycol or mixtures of glycols. The preferred monomer is styrene. Preferred suspending fillers and thixotropic modifiers include silica, microspheres, glass fibers and other short fibers, nepheline syenite, feldspar, mica, pumice, magnesium sulfate, calcium carbonate, bentonite and the various clays and thixotropic modifiers and mixtures thereof. Preferred phosphorescent pigments include alkaline earth aluminate phosphors, zinc sulfide phosphors and mixtures of these phosphors. The luminescent resins may be rendered fire retardant and made flexible. As the heavy phosphorescent pigments remain in suspension, the raw luminescent resins are suitable for long-term storage and use.
