摘要： This invention provides a material for adhesion prevention that can be adhered to biological tissue with certainty and has improved tissue adhesiveness and biodegradability. Such material for adhesion prevention is composed of: a 1- to 1,000-µm-thick water-soluble support layer comprising a water-soluble polymer; and a 1- to 1,000-µm-thick adhesion prevention layer comprising a biodegradable polymer. The biodegradable polymer has a structure in which a branched polyalkylene glycol comprising 3 to 8 terminal hydroxyl groups per molecule is bound to a polyhydroxy alkanoic acid, and a mass ratio of the branched polyalkylene glycol relative to the total mass is 1% to 30%.

摘要： The present invention provides dyed artificial leather including ultrafine fibers and a polymeric elastomer, having no color unevenness between the ultrafine fibers and the polymeric elastomer, and having good surface quality with high washing fastness, rubbing fastness, and light fastness, and also provides a production method therefor. The dyed artificial leather according to the invention includes a fibrous base containing ultrafine fibers with a filament fineness of 2 decitex or less and a polymeric elastomer, and characterized in that the lightness difference ΔL* between the ultrafine fibers and the polymeric elastomer represented by the following equation meet the requirement of -16≤ΔL*≤5: ΔL * = average lightness L * of ultrafine fibers − average lightness L * of polymeric elastomer .
The production method for dyed artificial leather according to the present invention is characterized by including a first dying step in which artificial leather constituted mainly of a fibrous base containing ultrafine fibers with a filament fineness of 2 decitex or less and a polymeric elastomer is dyed using a dye and a subsequent second dyeing step performed at a dye concentration that is 0.1% to 30% of the dye concentration (owf) in the first dyeing step.
