Coating composition containing crosslinkable monomeric difunctional compounds having at least thirty carbon atoms

A method of making a cured coated subtrate having improved scratch and mar resistance, comprising

• applying a coating composition to a substrate to make a coated substrate, the coating composition comprising
• (a) a reactive component which is not a crystalline solid at room temperature and is substantially free of any heteratoms, and comprising
• (i) from 12 to 72 carbon atoms, and
• (ii) at least two functional groups, and
• (b) a crosslinking agent comprising a plurality of functional groups (iii) reactive with the functional groups (ii) of compound (a) and which, upon reaction with at least one of the functional groups (ii) of compound (a), forms a thermally irreversible chemical linkage, and
• curing the curing the coated substrate to provide a cured coated substrate.

A coating composition comprising

• (a) a reactive component which is substantially free of any heteroatoms, comprises a mixture of at least one aliphatic compound, at least one aromatic containing compound, and at least one cycloaliphatic containing compound and comprises
• (i) from 12 to 72 carbon atoms, and
• (ii) at least two functional groups, and
• (b) a crosslinking agent comprising a plurality of functional groups (iii) reactive with the functional groups (ii) of compound (a),
• wherein functional groups (ii) and (iii) are selected such that reaction there between produces a thermally irreversible chemical.
