Abstract
Abstract Hypoallergenic jewelry and a method of making the same is achieved by providing vapor deposition of unsubstituted and substituted linear homopolymers and copolymers of poly(p-xylylene) on the jewelry having a thickness in the range of about 0.5 microns to about 25 microns. A new use of preventing allergic reactions when jewelry is worn is achieved by providing the jewelry with a poly(p-xylylene) polymer coating which provides a hypoallergenic surface on the jewelry.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
73 words
An article of manufacture adapted to be worn in juxtaposition to a living human or animal body, comprising: a metal substrate containing at least a predetermined small amount of an allergen; and a coating applied to and bonded to said metal substrate, said coating being comprised of a layer of poly(p-xylylene) polymer to provide a hypoallergenic surface on said metal substrate to eliminate the formation of an allergenic reaction by said living body.
Claim 2
Dependent Claim
73 words
An article of manufacture adapted to be worn in juxtaposition to a living human or animal body, comprising: a metal substrate containing at least a predetermined small amount of an allergen; and a coating applied to and bonded to said metal substrate, said coating being comprised of a layer of poly(p-xylylene) polymer to provide a hypoallergenic surface on said metal substrate to eliminate the formation of an allergenic reaction by said living body.

Claim 13
Dependent Claim
47 words
A new use for a poly(p-xylylene) polymer coating being the application of said coating to a substrate containing an allergen which is adapted to be worn in contact with a living body and thereby preventing an allergic reaction when the substrate is worn on a living body.
Claim 14
Dependent Claim
47 words
A new use for a poly(p-xylylene) polymer coating being the application of said coating to a substrate containing an allergen which is adapted to be worn in contact with a living body and thereby preventing an allergic reaction when the substrate is worn on a living body.
Claim 15
Dependent Claim
47 words
A new use for a poly(chloro-p-xylylene) polymer coating being the application of said coating to a substrate containing an allergen which is adapted to be worn in contact with a living body and thereby preventing an allergic reaction when the substrate is worn on a living body.
Claim 16
Dependent Claim
47 words
A new use for a poly(chloro-p-xylylene) polymer coating being the application of said coating to a substrate containing an allergen which is adapted to be worn in contact with a living body and thereby preventing an allergic reaction when the substrate is worn on a living body.
Claim 17
Dependent Claim
62 words
A process comprising the steps of: selecting metal substrates that are adapted to be placed in contact with a living human or animal body; determining the likelihood that said selected metal substrates may contain an allergen selected from the group consisting of nickel and chromates; and coating said selected metal substrates that are determined to contain an allergen with a poly(p-xylylene) polymer.
Claim 18
Dependent Claim
62 words
A process comprising the steps of: selecting metal substrates that are adapted to be placed in contact with a living human or animal body; determining the likelihood that said selected metal substrates may contain an allergen selected from the group consisting of nickel and chromates; and coating said selected metal substrates that are determined to contain an allergen with a poly(p-xylylene) polymer.
