<p>PURPOSE:To obtain the subject composition consisting of an oil-soluble bye, organic solvent, surfactant, a resin and a hygroscopic basicity imparting agent and capable of brightly and well transferring to a test piece of a freshly mixed concrete used for strength test of the freshly mixed concrete. CONSTITUTION:This oily ink composition consists of (A) an oil-soluble dye, (B) an organic solvent (usually a solvent for oily ink, e.g. Methyl Cellosolve), (C) a surfactant, (D) a resin (usually a resin used in oily ink and soluble in the component B, e.g. a ketone-based resin, etc.) and (E) a hygroscopic basicity imparting agent (e.g. monoethanolamine or dibutylaminepropanolamine). Furthermore, these components are preferably blended so as to contain 1-20wt.% component A, 40-90wt.% component B, 2-20wt.% component C, 0.1-5wt.% component D and 1-20wt.% component E based on the total amount of the ink composition.</p> |
