A method of ink jet recording including forming an uncured first ink layer of a first ultraviolet curable ink A on a recording medium, forming an uncured second ink layer having a recording pattern inside the uncured first ink layer of the ink A by discharging a second ultraviolet curable ink B from an ink jet head, and curing the uncured first ink layer by irradiating the uncured first ink layer with ultraviolet light after forming the uncured second ink layer, wherein the ink A contains a photoradical generator and the ink B contains a photobase generator and a coloring agent.

Ink jet recording method

A baseball game is provided which imitates reality more closely by reflecting player data in game characters. Data relating to good hitting courses and bad hitting courses for each batter are incorporated as batter parameters, and the selection of a good or bad course by the batter can be reflected in the result of a hit, by varying the size of a collision object, or the like, in accordance with the batter parameters.
