Abstract
Abstract A thermal detector and method of making the same in which a suspension of binder-encapsulated copper particles is produced by comminuting a chip formed by dry-milling a major amount of copper particles with a minor amount of a binder and a charge director to produce the chip of copper particles in an encapsulant having functional sites. The bits of comminuted material are wet-milled with a major amount of a low-boiling aliphatic hydrocarbon to produce a suspension from which encapsulated copper particles are deposited on a substrate by electrophoresis. The deposit is electron-beam cured to form the detector.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
69 words
A thermal detector including in combination a carrier and a coating of copper particles deposited thereon, said copper particles being encapsulated in a binder comprising a thermoplastic polymer which is insoluble in a low-boiling aliphatic hydrocarbon liquid at ambient or room temperatures and is softenable at temperatures above 70° C., said binder having a plurality of functional sites and having a minor amount of a charge director incorporated therein.
Claim 2
Dependent Claim
69 words
A thermal detector including in combination a carrier and a coating of copper particles deposited thereon, said copper particles being encapsulated in a binder comprising a thermoplastic polymer which is insoluble in a low-boiling aliphatic hydrocarbon liquid at ambient or room temperatures and is softenable at temperatures above 70° C., said binder having a plurality of functional sites and having a minor amount of a charge director incorporated therein.
Claim 3
Dependent Claim
19 words
A thermal detector including in combination a substrate and a layer of binder-encapsulated copper particles carried by said substrate.
Claim 4
Dependent Claim
19 words
A thermal detector including in combination a substrate and a layer of binder-encapsulated copper particles carried by said substrate.
Claim 5
Dependent Claim
