- (b) drying said coated substrate at a temperature of from 50 to 150.degree. C.;
- wherein formula (I) is ##STR4## where R.sub.1 represents a hydrogen atom or a methyl,
- R.sub.2 and R.sub.3 each represent a hydrogen atom or an alkyl group having from 1 to 4 carbon atoms, and
- n represents an integer from 2 to 4; and said ethylene copolymer has a melt index, as measured in accordance with JIS K-6760, of from 10 to 1,000 g/10 min.
- 3. A laminate for electrographic recording comprising:
- a substrate,
- a semi-conductive layer on said substrate, and
- a dielectric layer on said semi-conductive layer;
- wherein said semi-conductive layer is formed by
- (a) coating said substrate with an aqueous dispersion of a cationic polymer obtained by
- (i) reacting an ethylene copolymer, comprising from 40 to 80% by weight of ethylene and from 20 to 60% by weight of at least one aminoalkyl acrylamide comonomer represented by formula (I), with hydrochloric acid in water to form a quaternary salt, and
- (ii) reacting said quaternary salt with an epihalohydrin compound through an addition reaction; and
- (b) drying said coated substrate at a temperature of from 50 to 150.degree. C.; and
- said dielectric layer is formed by
- (a) coating said semi-conductive layer with a dielectric resin and
- (b) drying said dielectric resin at a temperature of from 50 to 150.degree. C.;
- wherein formula (I) is ##STR5## where R.sub.1 represents a hydrogen atom or a methyl,
- R.sub.2 and R.sub.3 each represent a hydrogen atom or an alkyl group having from 1-4 carbon atoms, and
- n represents an integer from 2 to 4; and
- said ethylene copolymer has a melt index, as measured in accordance with JIS K-6760, of from 10 to 1,000 g/10 min.
- 4. A laminate for electrographic recording comprising:
- a substrate,
- a semi-conductive layer on said substrate, and
- a dielectric layer on said semi-conductive layer; wherein said semi-conductive layer is formed by
- (a) coating said substrate with an aqueous dispersion of a cationic polymer obtained by
- (i) reacting an ethylene copolymer, comprising from 40 to 80% by weight of ethylene and from 20 to 60% by weight of at least one aminoalkyl acrylamide comonomer represented by formula (I), with hydrochloric acid in water to form a quaternary salt, and
- (ii) reacting said quaternary salt with an epihalohydrin compound through an addition reaction, and
- (iii) reacting the product of said reaction (ii) with an alkylolamine compound; and
- (b) drying said coated substrate at a temperature of from 50 to 150.degree. C.; and
- said dielectric layer is formed by
- (a) coating said semi-conductive layer with a dielectric resin and
- (b) drying said dielectric resin at a temperature of from 50 to 150.degree. C.;
- wherein formula (I) is ##STR6## where R.sub.1 represents a hydrogen atom or a methyl,
- R.sub.2 and R.sub.3 each represent a hydrogen atom or an alkyl group having from 1-4 carbon atoms, and
- n represents an integer from 2 to 4; and said ethylene copolymer has a melt index, as measured in accordance with JIS K6760, of from 10 to 1,000 g/10 min.
