The present disclosure provides an anti-adhesion composition for wound protection in the form of a film comprising a biocompatible mucoadhesive polymer and a specific swellable polymer. The present disclosure relates to an anti-adhesion agent that is flexible and adheres appropriately to an application site by improving crumbling and adhesion properties, which are problems of existing film-type anti-adhesion agents.

A wound dressing which is removable with little or no adhesion to wounded tissue includes a wound contact layer. The wound contact layer comprises molecules which can be rapidly degraded by exposure to certain light, and non-sticking molecules. The photodegradable molecules includes at least one o-nitrobenzyl group.

A polymer film can be adjusted to movement or a fine uneven surface of a living body and has excellent ability to adhere to a biological tissue. The polymer film includes a block copolymer having a structure in which branched polyalkylene glycol and polyhydroxyalkanoic acid are bound to each other, wherein the polymer film has a film thickness of 10 to 1000 nm. The branched polyalkylene glycol has at least three terminal hydroxyl groups per molecule, the mass percentage of the branched polyalkylene glycol relative to the total mass of the block copolymer is 1% to 30%, and a value obtained by dividing the average molecular weight of polyhydroxyalkanoic acid in the block copolymer by X that is the number of terminal hydroxyl groups present per a single molecule of the branched polyalkylene glycol is 10000 to 30000.

Our invention is a laminate film comprising a water-soluble resin layer and a polylactic acid-based resin layer laminated on at least one side of a substrate film, the water-soluble resin layer has a thickness of 0.1 to 15 m, the polylactic acid-based resin layer has a thickness of 10 to 500 nm. Such a configuration provides a laminate film of which the water-soluble resin layer and the polylactic acid-based resin layer are easily separated from the substrate film and which is excellent in coating ability, adherence and followability to a soft and curved adherend, as well as compatibility to skin and organs such as viscera, so as to be suitable for wound dressing, adhesion prevention material and a skin external agent such as skin-care product.
