ABSTRACT OF THE DISCLOSURE A polyurethane one-component heat-curing coating material which is stable in storage and is hardened above a temper- ature of about 120°C, comprising a polyol compound having a low glass transition temperature, and a blocked polyisocyanate com- pound, wherein the blocked polyisocyanate compound is the reaction product of a polyisocyanate compound and a secondary amine com- pound having the formula: Image wherein R is selected from the group consisting of hydrogen atom, C3-C9 alkyl radical, unsubstituted cycloalkyl radical, cycloalkyl radical substituted by C1-C4 alkyl radicals, heteroatom-containing cycloalkyl radical, unsubstituted aralkyl radical, aralkyl radical substituted by C1-C4 alkyl radicals, or heteroatom- containing aralkyl radical, wherein each R is identical to or different from each other; R1 is selected from the group con- sisting of alkyl radical, cycloalkyl radical, or aralkyl radical, wherein each R1 is identical to or different from each other; or R and R1 are chemically bonded therebetween, thereby forming a ring structure.
