<p>The present invention addresses the problem of providing a copolymer composition for screen printing, which is suitable for an adhesive for touch panels, said adhesive requiring a short time for bonding a substrate and being free from curing unevenness. The present invention relates to a copolymer composition for screen printing, which is characterized by containing an ethylene/alpha-olefin/non-conjugated polyene random copolymer (A) that satisfies the conditions (a)-(c) described below and contains a constituent unit [i] derived from ethylene, a constituent unit [ii] derived from an alpha-olefin having 3-20 carbon atoms and a constituent unit [iii] derived from a specific non-conjugated polyene. (a) The molar ratio of the ethylene unit [i] to the alpha-olefin unit [ii] ([i]/[ii]) is from 35/65 to 95/5. (b) The iodine number is within the range of 0.5-50. (c) The limiting viscosity [eta] as measured in a decalin solution at 135°C is within the range of 0.01-5.0 (dl/g).</p> |
