  • Patent number: 9529287
    Abstract: A recording sheet is produced by coating and drying on a support formed of a thermoplastic resin film a coating solution containing an olefin copolymer emulsion having a solid content of 100 parts by mass and a silane coupling agent having a solid content of from 2 to 14 parts by mass to form a surface treatment layer having a solid content of from 0.1 to 5 g/m2. The recording sheet has high adhesion property between the support layer and the surface treatment layer, is capable of being subjected to various kinds of printing including offset printing and flexographic printing, and particularly has excellent adhesion property between the surface treatment layer and the toner to prevent the toner from being dropped off even in the case where the recording sheet is subjected to an electrophotographic recording printing process using a liquid toner.
