Abstract
Abstract A coating composition for application to surfaces previously coated with lead paint or other poisonous substances comprising a paint containing a bitter tasting component such as denatonium benzoate. This coating composition has a repulsive taste and an appearance similar to ordinary paints so that it will impart an unpleasant taste experience to a child who mouths surfaces or chips coated with it and will condition the child to avoid mouthing surfaces or chips of similar appearance.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
116 words
A coating composition for application to previously coated substrates consisting essentially of a paint containing 0.05% to 0.5% by weight of the non-volatile portion of said paint of a bitter tasting deterrent selected from the group consisting of at least one of denatonium benzoate and lignocaine benzyl octanoate; 9.0% to 99.5% by weight of a latex resin binder for controlling the amount of said deterrent released on contact with saliva; and an effective amount of a surfactant for stabilization of said paint, said coating composition having the visual appearance, durability, adhesion, toughness, washability and continuity of conventional paint and having a repulsive taste which discourages persons from licking, sucking, chewing, swallowing or otherwise mouthing said substrates.
Claim 2
Dependent Claim
116 words
A coating composition for application to previously coated substrates consisting essentially of a paint containing 0.05% to 0.5% by weight of the non-volatile portion of said paint of a bitter tasting deterrent selected from the group consisting of at least one of denatonium benzoate and lignocaine benzyl octanoate; 9.0% to 99.5% by weight of a latex resin binder for controlling the amount of said deterrent released on contact with saliva; and an effective amount of a surfactant for stabilization of said paint, said coating composition having the visual appearance, durability, adhesion, toughness, washability and continuity of conventional paint and having a repulsive taste which discourages persons from licking, sucking, chewing, swallowing or otherwise mouthing said substrates.
Claim 3
Dependent Claim
108 words
A coating composition for application to previously coated substrates consisting essentially of a paint containing 0.05% to 0.5% by weight of the non-volatile portion of said paint of the bitter tasting deterrent lignocaine benzyl octanoate; 9.0% to 99.5% by weight of a resin binder consisting of polyvinyl acetate-acrylic copolymer latex for controlling the amount of said deterrent released on contact with saliva; and an effective amount of a surfactant for stabilization of said paint, said coating composition having the visual appearance, durability, adhesion, toughness, washability and continuity of conventional paint and having a repulsive taste which discourages persons from licking, sucking, chewing, swallowing or otherwise mouthing said substrates.
Claim 4
Dependent Claim
108 words
A coating composition for application to previously coated substrates consisting essentially of a paint containing 0.05% to 0.5% by weight of the non-volatile portion of said paint of the bitter tasting deterrent lignocaine benzyl octanoate; 9.0% to 99.5% by weight of a resin binder consisting of polyvinyl acetate-acrylic copolymer latex for controlling the amount of said deterrent released on contact with saliva; and an effective amount of a surfactant for stabilization of said paint, said coating composition having the visual appearance, durability, adhesion, toughness, washability and continuity of conventional paint and having a repulsive taste which discourages persons from licking, sucking, chewing, swallowing or otherwise mouthing said substrates.
Claim 5
Dependent Claim
16 words
A coating composition as defined by claim 2 wherein said surfactant is nonyl phenoxy polyoxyethylene ethanol.
Claim 6
Dependent Claim
30 words
A coating composition as defined by claim 2 which further contains effective amounts of an anti-foam agent and a coalescing agent, said anti-foam and coalescing agents providing proper film formation.
Claim 7
Dependent Claim
17 words
A coating composition as defined by claim 4 wherein said coalescing agent is 2,2,4 trimethylpentane diol monoisobutyrate.
Claim 8
Dependent Claim
34 words
A coating composition as defined by claim 2 which further contains effective amounts of an opacifying pigment to provide the visual appearance of ordinary paint and a thickener to prevent settling of said pigment.
Claim 9
Dependent Claim
14 words
A coating composition as defined by claim 6 wherein said thickener is methyl cellulose.
Claim 10
Dependent Claim

A coating composition as defined by claim 2 which further contains effective amounts of an antifreeze agent to protect said paint against exposure to low temperatures and a non-toxic preservative to prevent deterioration of the paint due to bacterial attack.
Claim 11
Dependent Claim
21 words
A coating composition as defined by claim 8 wherein said antifreeze agent is ethylene glycol and said preservative is 2-[(hydroxymethyl)amino] ethanol.
Claim 12
Dependent Claim
60 words
A paint additive consisting essentially of a solution of an effective amount of the bitter tasting deterrent lignocaine benzyl octanoate and a solvent, said paint additive when added to a coating compound providing a product having the visual appearance of conventional paint and having a repulsive taste which discourages persons from licking, sucking, chewing, swallowing or otherwise mouthing said substrates.
Claim 13
Dependent Claim
60 words
A paint additive consisting essentially of a solution of an effective amount of the bitter tasting deterrent lignocaine benzyl octanoate and a solvent, said paint additive when added to a coating compound providing a product having the visual appearance of conventional paint and having a repulsive taste which discourages persons from licking, sucking, chewing, swallowing or otherwise mouthing said substrates.
Claim 14
Dependent Claim
25 words
A paint additive as defined by claim 10 wherein said solvent is selected from the group consisting of ethylene glycol, propylene glycol, water and alcohol.
