| abstract |
A slipping property imparting agent for use in clear coating, which comprises a copolymer containing an unsaturated olefin (component (a)) and an unsaturated carboxylic acid (salt) (component (b)) as copolymerization components, wherein preferably, the component (a) accounts for 50 to 99 mole % and the component (b) accounts for 50 to 1 mole % relative to the total mole of the component (a) and the component (b) and, optionally, the copolymer further contains a component (c) being copolymerizable with the component (a) and the component (b) in an amount up to 20 mole % relative to the total mole of the component (a) and the component (b). The use of the slipping property imparting agent allows the reduction in the formation of scum during coating. |
