Title:

RESIN FOR THERMAL IMPRINTING

Document Type and Number:

WIPO Patent Application WO/2007/066712

Kind Code:

A1

Abstract:

A cycloolefin thermoplastic resin for thermal imprinting to be used in the production of sheets or films which contains in the backbone chain at least one kind of skeletons represented by [Chemical formula 1] or [Chemical formula 2], characterized in that the glass transition temperature Tg(°C) of the resin and MFR ([M]) thereof at 260°C satisfy the relationship (1) and [M] is less than 30. This resin is excellent in thermal imprintability (such as transfer property and mold release property) and contributes to improvement in the productivity (such as throughput): Tg(°C) > 219 × log[M] - 160 ... relationship (1)
