A pigmented curable composition adapted for decorating ceramic substrates (e.g., glass bottles) comprises curable organic binder and solid spherical particles (glass or polymer) having diameters of 10 to 50 microns for facilitating overprinting of additional layers. The preferred embodiment comprises: (a) reactive organic resin component in which epoxy groups comprise the major reactive functionality; (b) amino-functional curing agent; (c) blocked polyisocyanate; and (d) 5 to 35 percent solid spherical particles having diameters of 10 to 50 microns.

Method and compositions for applying multiple overlying organic pigmented decorations on ceramic substrates

A coated plastic or high pressure laminated article and a process for making same includes coating a plastic or high pressure laminated substrate with a radiation curable top coat which may include ultraviolet inhibitors therein. The radiation curable top coat is subjected to a curing step which includes curing with either an electron beam, ultraviolet radiation or a combination thereof. The resulting article is a coated article which is comprised of a substrate coated with a radiation cured coating having an outer surface susceptible for receiving a sublimatable ink diffused therein.

Process for making a radiation-cured coated article

A coated cement board article capable of receiving a sublimatable ink and a process for making same includes coating a cement board substrate with a radiation curable top coat. The radiation curable top coat is subjected to a curing step which includes curing with either an electron beam, ultraviolet radiation or a combination thereof. A sublimatable ink may be transferred into the top coat.

Process for making a radiation cured cement board substrate

A cured coated article and a process for making same includes coating a substrate, such as wood, plastic, high pressure laminates, ceramic or metal with a radiation curable top coat having UV protectable additives therein. The radiation curable top coat is subjected to a curing step which includes curing with either an electron beam, ultraviolet radiation or a combination thereof. A sublimatable ink may be transferred into the top coat.

Process for making an ultraviolet stabilized substrate

This invention provides for a coating composition comprising: (A) at least one polymeric material selected from (i) at least one homopolymer of ethylene having a melt index of at least about 220 grams per ten minutes as determined by ASTM D1238, condition 190/2.16, or (ii) at least one copolymer of ethylene and a second ethylenically unsaturated monomer having a melt index of at least about 20 grams per ten minutes as determined by ASTM D1238, condition 190/2.16, or (iii) at least one thermoplastic acrylic homopolymer or copolymer having a glass transition temperature (Tg) of greater than 0.degree. C. but less than 110.degree. C., or (iv) a mixture of (i), (ii) and/or (iii); and (B) at least one thermoplastic polymeric material different than (A) having a melting point in the range of about 80.degree. C. to about 130.degree. C. and being miscible with (A) and wherein the viscosity of the polymer composition (A) and (B) is in the range of about 5,000 cps to about 100,000 cps at a temperature range of about 200.degree. F. to about 300.degree. F. The invention further provides for a process for applying the foregoing coating composition to a substrate such as glass, ceramic, metal, fiberboard, textile or plastic substrate (e.g., glass jars or bottles) preferably using hot melt screen printing; the process employs a low-temperature cure that requires only a relatively brief cure time (e.g., less than about one second). The coating composition can be reheated to obtain higher gloss and/or enhance the adhesion of the coating to the substrate.

Thermoplastic coating compositions and process using same

The present invention provides a screen printable coating composition comprising one or more hydroxy functional materials (I), one or more crosslinkers (II) for curing the hydroxy functional materials, and one or more crystalline reactive diluents (III). The coating composition may also include one or more catalysts (IV), plasticizers (V), rheology modifiers (VI), waxes (VII) and coloring agents (VIII). Various additives and fillers may also be included in the coating composition.
