Abstract
Abstract Improved decalcomanias suitable for high rate application to substrates and for the decoration of ceramic ware and the like contain a layer having low adhesion to a carrier layer, so that the carrier layer is readily removable after application of the decalcomania to a substrate. The desired low adhesion is achieved by the introduction of wax into the decal layer or by incorporating oil in a preprint lacquer layer between the decal layer and the carrier.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
101 words
A DECALCOMANIA SUITABLE FOR APPLICATION TO A CERAMICSUBSTRATE AT HIGH RATE CONSISTING ESSENTIALLY OF A CARRIER LAYER, AN OVERLYING DECAL LAYER CONTAINING VITRIFIABLE PIGMENT AND A THERMOSPLASTIC RESIN, AND AN AGENT FOR FACILITATING THE SEPARATION OF SAID DECAL LAYER FROM SAID CARRIER LAYER, SAID AGENT CONSISTING ESSENTIALLY OF A MEMBER SELECTED FROM THE GROUP CONSISTING OF A WAX IN SAID DECAL LAYER AND A PREPRINT LACQUER LAYER BETWEEN SAID DECAL LAYER AND SAID CARRIER LAYER, SAID PREPINT LACQUER CONTAINING A QUALITY OF OIL EFFECTIVE FOR FACILITATING SAID SEPARATION SAID WAX BEING SELECTED FROM THE GROUP CONSISTING OF POLYETHYLENE AND POLYETHYLENE GLYCOL.

A DECALCOMANIA SUITABLE FOR APPLICATION TO A CERAMICSUBSTRATE AT HIGH RATE CONSISTING ESSENTIALLY OF A CARRIER LAYER, AN OVERLYING DECAL LAYER CONTAINING VITRIFIABLE PIGMENT AND A THERMOSPLASTIC RESIN, AND AN AGENT FOR FACILITATING THE SEPARATION OF SAID DECAL LAYER FROM SAID CARRIER LAYER, SAID AGENT CONSISTING ESSENTIALLY OF A MEMBER SELECTED FROM THE GROUP CONSISTING OF A WAX IN SAID DECAL LAYER AND A PREPRINT LACQUER LAYER BETWEEN SAID DECAL LAYER AND SAID CARRIER LAYER, SAID PREPINT LACQUER CONTAINING A QUALITY OF OIL EFFECTIVE FOR FACILITATING SAID SEPARATION SAID WAX BEING SELECTED FROM THE GROUP CONSISTING OF POLYETHYLENE AND POLYETHYLENE GLYCOL.
Claim 3
Dependent Claim
13 words
A decalcomania as defined in claim 1, wherein said thermoplastic resin is polybutylmethacrylate.
Claim 4
Dependent Claim
53 words
A decalcomania as defined in claim 1 further comprising a finishing adhesive layer containing a thermoplastic resin overlying said decal layer, thereby causing said decal layer to adhere to a substrate when said decalcomania is applied to said substrate and heated to a temperature high enough to render said finishing adhesive layer tacky.
Claim 5
Dependent Claim
30 words
A decalcomania as defined in claim 3, wherein said thermoplastic-containing layer when deposited on said decal layer comprises at least one thermoplastic resin, a plasticizer and at least one solvent.
Claim 6
Dependent Claim
41 words
A decalcomania as defined in claim 1, wherein said decal layer when deposited contains a pigment, a thermoplastic resin, a wax selected from the group consisting of high molecular weight polyethylene and high molecular weight polyglycol, a plasticizer and a solvent.
Claim 7
Dependent Claim
23 words
A decalcomania as defined in claim 5, wherein said pigment constitutes from one-half to two-thirds of said decal layer by weight as deposited.
Claim 8
Dependent Claim
23 words
A decalcomania as defined in claim 1, wherein said carrier is a paper permeable to water and is coated with glue or dextrin.
Claim 9
Dependent Claim
14 words
A decalcomania as defined in claim 1, wherein said carrier is a metal foil.
Claim 10
Dependent Claim
39 words
A decalcomania as defined in claim 1, wherein said preprint lacquer layer contains sufficient oil to weaken any bond between said preprint layer and said carrier, thereby making it possible to strip said carrier from said preprint lacquer layer.
Claim 11
Dependent Claim
73 words
A DECALCOMANIA SUITABLE FOR APPLICATION TO A CERAMIC SUBSTRATE AT HIGH RATE CONSISTING ESSENTIALLY OF A CARRIER LAYER PERMEABLE TO WATER AND COATED WITH DEXTRIN OR GLUE, A OVERLYING DECAL LAYER CONTAINING VITRIFIABLE PIGMENT, WAX, AND A THRMOSPLASTIC RESIN, AND A FINISHING LAYER CONTAINING THERMOPLASTIC RESIN OVERLYING SAID PIGMENT-CONTAINING DECAL LAYER, SAID CARRIER BEING DETACHABLE FROM SAID DECAL LAYER BY WETTING SAID CARRIER SUBSEQUENT TO ATTACHING SAID DECALCOMANIA TO A SUBSTRATE BY HEATING.
