HIGH-INTENSITY INK COMPOSITION, HIGH-INTENSITY BASE PAPER, AND THERMOSETTING RESIN BOARD

摘要

Provided are: a high-intensity ink composition which has an excellent high-intensity appearance and finish and excellent adhesiveness to a base paper, and which facilitates excellent impregnation of a thermosetting resin into the base paper; a high-intensity base paper using said high-intensity ink composition; and a thermosetting resin board using said high-intensity base paper. The present invention relates to a high-intensity ink composition that includes a high-intensity pigment having an average particle size of 10 μm or more, and a casein resin, a urethane resin and a cellulose resin serving as a mixed resin, wherein the mass ratio (P/V ratio) of the high-intensity pigment and the mixed resin is 1-3, the mass ratio of the cellulose resin, the casein resin, and the urethane resin is 0.005-0.05. The present invention also relates to a high-intensity base paper using said ink composition, and a thermosetting resin board using said high-intensity base paper.
