Abstract
Abstract An electrically conductive, curable composition comprising as its main components, cyanoacrylates and metal powder and having a superior storage stability, curability at room temperature and a superior electrical conductivity after being cured, which is useful as a quick-curing adhesive, is provided, wherein the cyanoacrylate or/and the metal powder is treated so as to prevent or inhibit the property of the powder of inducing cyanoacrylate polymerization.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
40 words
An electrically conductive powder for mixing with cyanoacrylates, which consists of a metal powder treated with a substance which reacts with water or/and acidifies water, so as to prevent or inhibit the property of metal powder of inducing cyanoacrylate polymerization.
Claim 2
Dependent Claim
40 words
An electrically conductive powder for mixing with cyanoacrylates, which consists of a metal powder treated with a substance which reacts with water or/and acidifies water, so as to prevent or inhibit the property of metal powder of inducing cyanoacrylate polymerization.
Claim 3
Dependent Claim
78 words
An electrically conductive metal powder for mixing with cyanoacrylates according to claim 1 wherein said substance is at least one compound selected from the group consisting of halides of elements of the groups III to VI of the Periodic Table, elements of the group VII of the Periodic Table and oxygen compounds thereof, oxygen compounds having an acid anhydride group, substances which are readily hydrolyzed to produce acids and metal-containing organic compounds which are readily reactive with water.
Claim 4
Dependent Claim
61 words
An electrically conductive powder for mixing with cyanoacrylates according to claim 1 wherein said substance which prevents orinhibitsthe property of metal powder of inducing cyanoacrylate polymerization, by acidifying water is at least one compound selected from the group consisting of acidic compounds, carboxylic acids and halogen acids, each containing elements of the groups III, V and VI of the Periodic Table.
Claim 5
Dependent Claim
43 words
An electrically conductive, curable composition comprising as its main components, one or more cyanoacrylates and a metal powder treated with a substance which reacts with water or/and acidifies water to thereby prevent or inhibit the property of metal powder of inducing cyanoacrylate polymerization.
Claim 6
Dependent Claim
43 words
An electrically conductive, curable composition comprising as its main components, one or more cyanoacrylates and a metal powder treated with a substance which reacts with water or/and acidifies water to thereby prevent or inhibit the property of metal powder of inducing cyanoacrylate polymerization.
Claim 7
Dependent Claim
20 words
An electrically conductive, curable composition according to claim 4, further comprising a substance which reacts with water or/and acidifies water.
Claim 8
Dependent Claim
78 words
An electrically conductive, curable composition according to claim 4 wherein said substance which reacts with water is at least compound selected from the group consisting of halides of elements of the groups III to VI of the Periodic Table, simple elements of the group VII of the Periodic Table and oxygen compounds thereof, oxygen compounds having an acid anhydride group, substances which are readily hydrolyzed to produce acids and metal-containing organic compounds which are readily reactive with water.
Claim 9
Dependent Claim
78 words
An electrically conductive, curable composition according to claim 5 wherein said substance which reacts with water is at least compound selected from the group consisting of halides of elements of the groups III to VI of the Periodic Table, simple elements of the group VII of the Periodic Table and oxygen compounds thereof, oxygen compounds having an acid anhydride group, substances which are readily hydrolyzed to produce acids and metal-containing organic compounds which are readily reactive with water.
Claim 10
Dependent Claim
50 words
An electrically conductive, curable composition according to claim 4 or claim 5, wherein said substances which acidifies water is at least one compound selected from the group consisting of acidic compounds, carboxylic acids and halogen acids, each containing elements of the groups III, V and VI of the Periodic Table.
