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 forma 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.

Abstract: Provided is a labeled container that is easily peeled off when being scrapped, while having sufficient adhesion. The labeled container comprises a label having a heat sealing layer, and a resin container to which the label is attached through the heat sealing layer. A part of the label is embedded in the resin container, and a notch portion is provided around the label on the surface of the resin container. The notch portion has a depth (d) of 40 μm or more. The notch portion has a width (L) of 300 μm or more. One selected from the resin container and the heat sealing layer on the attached surfaces contains a polyolefin resin as a main component, and the other contains a polyester resin as a main component.
