To provide a radiation-curable ink composition that can form a high-quality image on not only liquid absorbing materials to be recorded but also non-liquid absorbing materials to be recorded, is superior in curing properties in air, and is superior in storage stability, color tone, light fastness and water resistance of ink, and also to provide an image recording method. The radiation-curable ink composition comprises a monomer having a polymerizable group selected from the group consisting of an acryloyl group, a methacryloyl group, an allyl group, and a vinyl group, an oil-soluble dye, and from 0.005 to 1% by weight of a storage stabilizer, wherein the oil-soluble dye is dissolved in the ink.

Radiation-curable ink composition and image recording method

The invention provides a liquid developer for photographic silver halide photosensitive material comprising a silver halide emulsion layer containing at least 50% based on the projected area of tabular silver halide grains with an aspect ratio of at least 3.0 and having a swelling factor of 130-250%. In the liquid developer containing ascorbic acid or a derivative thereof as a developing agent or preservative, a compound of formula (I): ##STR1## wherein each of R.sub.1 and R.sub.2 is a C1-C3 hydroxyalkyl group or C1-C3 alkyl group and R.sub.3 is a C1-C3 hydroxyalkyl group is added for preventing the developer from coloring with the lapse of time.
