Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
192 words
A recording method comprising the steps of: jetting liquid droplets of an aqueous recording liquid onto a recording medium subjected to sizing and having fibers exposed on a surface thereof, wherein said aqueous recording liquid comprises 1 to 10% by weight of a water-soluble dye, at least 61% by weight of water, and at least one of the compounds represented by formulae (I), (II) or (III) below, wherein, if selected, said compound (I) is contained in said recording liquid within a range of 2 to 30% by weight, and said compounds (II) or (III) are contained within a range of 6 to 30% by weight based on the total weight of the recording liquid: R.sub.1 O--(C.sub.2 H.sub.4 O).sub.m --R.sub.2 (I) HO--(C.sub.2 H.sub.4 O).sub.a (C.sub.3 H.sub.6 O).sub.b (C.sub.2 H.sub.4 O).sub.c H (II) (R.sub.3)(R.sub.4)Ph--O--(C.sub.2 H.sub.4 O).sub.n H (III) wherein R 1 and R 2 are independently C 1-6 alkyl or C 8 or less aryl, m is from 3 to 20, a+c are at most 78, b is from 2 to 15, R 3 and R 4 are independently hydrogen or a C 1 or 2 alkyl, and n is from 4 to 20.
