Abstract
Abstract A free radical is effectively produced from an organic halogen compound having at least one halogen atom in a medium comprising an organic metal salt capable of being reduced by applying radiation energy to at least the organic metal salt. This free radical producing method can be used for recording. A photosensitive composition and article of manufacture based on the above-mentioned components irradiated with such radiation energy is also disclosed.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
63 words
A method of recording which comprises forming an image by imagewise exposing, with radiation capable of reducing an organic metal salt, a photosensitive material comprising an organic halogen compound having at least one halogen atom, an organic metal salt which can be reduced by radiation energy selected from the group consisting of metal oxalates, metal acetates, Cu(OH)2(CH3COO)4 and metal dithizones of the formula
Claim 2
Independent Claim
116 words
A method of recording which comprises employing a treating material composed mainly of an organic halogen compound having at least one halogen atom and an image forming material selected from the group consisting of arylamines, indoles, spiropyran compounds and acid-base indicators capable of forming an image by color change caused by reaction with at least one member of the group consisting of a free radical produced from said organic halogen compound and a halogen acid secondarily formed from said free radical, and a photosensitive member containing mainly an organic metal salt which can be reduced by a radiation energy selected from the group consistng of metal oxalates, metal acetates, Cu(OH)2(CH3COO)4 and metal dithizones of the formula
Claim 3
Independent Claim
116 words
A method of recording which comprises employing a treating material composed mainly of an organic halogen compound having at least one halogen atom and an image forming material selected from the group consisting of arylamines, indoles, spiropyran compounds and acid-base indicators capable of forming an image by color change caused by reaction with at least one member of the group consisting of a free radical produced from said organic halogen compound and a halogen acid secondarily formed from said free radical, and a photosensitive member containing mainly an organic metal salt which can be reduced by a radiation energy selected from the group consisting of metal oxalates, metal acetates, Cu(OH)2(CH3COO)4 and metal dithizones of the formula
