<p>PROBLEM TO BE SOLVED: To provide a screen printing ink having self-temperature control function for making self-temperature adjusting heating elements excellent in heat resistance with maintaining PTP characteristics even when external pressures such as folding, bending, pressurizing and the like are applied during their use. SOLUTION: This printing ink for self-temperature control heater is constituted of 100 pts.wt. of (A) an organic component comprising 30-70 wt.% of (a) a base polymer having 90-150 deg.C softening point, 10-50 wt.% of (b) a wax, 0-20 wt.% of (c) a polyol having 500-10,000 weight average molecular weight and 5-20 wt.% of (d) a dispersant and 30-70 pts.wt. of (B) electroconductive powder and 0-20 pts.wt. of (C) non-conductive organic or inorganic fine particles.</p> |
