A lawn colorant composition having rearing effects contains a pigment and an adhesive for the pigment. The pigment comprises a blue pigment composed as a primary component of a compound represented by the following formula: MFe&lsqb;Fe(CN) &rsqb; wherein M represents an alkali metal atom or an ammonium group, one of the two Fe atoms is a divalent ion, and the other Fe atom is a trivalent ion. The adhesive comprises a water-dispersed polymer and a water-soluble polymer having compatibility with said water-dispersed polymer.

A polyfunctional polycarbodiimide compound contains at least four molecular chains bonded independently to a backbone. Each of the molecular chains contains a carbodiimido (&mdash;N&boxH;C&boxH;N&mdash;) group. The polyfunctional carbodiimide compound can be produced by reacting (a) an isocyanate compound having at least one carbodiimido group and at least one isocyanate group with (b) a polyol, polyamine and/or aminoalcohol having at least four hydroxyl, primary amino and/or secondary amino groups in a molecule. Also disclosed are a resin composition containing the polyfunctional polycarbodiimide compound as a crosslinking agent; and a treatment method of an article, which makes use of the resin composition.
