摘要:
The organic polymer particles comprise a carboxyl group and 2,3-dihydroxypropyl group, and the magnetic particles for diagnostics comprise fine magnetic material particles and a polymer part containing a hydrophilic polymer part and a crosslinked polymer part, a dry coating film obtained from a water dispersion thereof having a contact angle with water of 5° to 60°. The process for producing the carboxyl group-containing particles comprises a step of producing an ester bond by reacting a hydroxyl group in organic polymer particles having the hydroxyl group with a carboxylic anhydride. The organic polymer particles comprise a hydroxyl group originating from a 2,3-dihydroxypropyl group and a polyoxyethylene group.

摘要:
On one surface of a normal paper sheet 1, patterns 2 are printed, and tabs 3 for sticking are printed at the outside portions of the outlines of the patterns 2. On the reverse sides of the patterns 2, sticky surfaces 4 are provided at corresponding portions to which the tabs 3 for sticking are to be stuck. On the side having sticky surfaces 4 are provided a release sheet 6 whose size is substantially the same as the paper sheet 1. Lines 7 for clipping are provided along the outlines of the patterns 2 and the tabs 3 for sticking. Lines 8 and 9 for folding are provided in an inside area of the lines for clipping. The patterns 2 and the tabs 3 for sticking are clipped along the lines 7 for clipping. The clipped patterns are fabricated into a three-dimensional toy by folding along the lines for folding. Then the tabs 3 for sticking are fixedly stuck to the sticky surfaces 4 which are on the reverse sides of the patterns 2.
