Abstract: A resin composition includes: a resin component comprising 50 to 100 parts by mass of (i-1) a polylactic acid and 50 to 0 part by mass of (i-2) a polyolefin [the total of (i-1) and (i-2) is 100 parts by mass], and 1 to 100 parts by mass, per 100 parts by mass of the resin component, of (ii) a functional group-containing, hydrogenated, diene-based polymer containing at least one kind of functional group selected from the group consisting of carboxyl group, acid anhydride group, epoxy group, (meth)acryl group, amino group, alkoxysilyl group, hydroxyl group, isocyanate group and oxazoline group; and a molded article thereof. The resin composition and the molded article are superior in balance between tensile property or stiffness and impact resistance as well as in appearance when molded and, moreover, have biodegradability (disintegratability); and, therefore, can be used in various applications such as packaging materials, industrial materials, industrial products, containers, medical tools and the like.

Abstract: A flexographic printing plate, which comprises a plate formed in a form of sheet from a composition 100 parts by mass of (A1) a thermoplastic elastomer and 0.1 to 50 parts by mass of (B) silica particles, and has an intended printing pattern formed on at least one side which is a side to be subjected to laser processing of the plate formed in a form of sheet for laser processing by subjecting the at least one side to laser processing for engraving. The flexographic printing plate has good flexibility but is not sticky at the processed surface, is superior in transparency, gives neither offensive odor nor flaming during laser processing, at an excellent engraving precision, can be produced easily and has a sufficient engraving depth.
