Novel hydrogenated resin produced from five-member cyclic compounds having a conjugated double bond and/or diels-alder addition products thereof

A resin composition comprising:

• a hydrogenated resin obtained by hydrogenating a copolymer resin which has been produced by copolymerizing a five-member cyclic compound (component A) selected from the group consisting of cyclopentadiene, dicyclopentadiene, and mixtures thereof with a codimer (component B) of cyclopentadiene with 1,3-butadiene selected from the group consisting of tetrahydroindene, vinylnorbornene, and mixtures thereof, by copolymerizing a mixture of 20 to 90 parts by weight of said component A with 80 to 10 parts by weight of said component B;
• and one constitutent selected from the group consisting of ethylenic copolymers and/or waxes;
• pigments and/or fillers;
• block-copolymers represented by the general formula of (A-B).sub.n or (A-B).sub.n-1 -A, wherein A is a non-elastomeric polymer block having a glass transition point of higher than 20.degree. C. and an average molecular weight ranging within 5,000 to 125,000, B is an elastomeric polymer block of a conjugated diene having an average molecular weight of 15,000 to 500,000, the polymer block A occupies less than 80 wt% of the block-copolymer and n is an integer of not less than 2;
• and natural and synthetic rubbers and mixtures thereof.
