Abstract: An improved magnetic game system according to the invention includes a magnetically attractable layer which has the same shape as a game track on the board's surface. The magnetically attractable layer is made of, for example, particles such as iron particles dispersed in a layer of a cross-linked, flexible polymeric material, such as an acrylic resin. The resulting board has improved durability and may be economically manufactured.

Abstract: A pre-printed spirit duplicating master. A liquid ink composition composed of 40% to 62% by weight of a dye, 40% to 65% by weight of an alcohol soluble polyamid resin having a melting point in the range of 110.degree. C. to 125.degree. C., and 12% to 25% by weight of ethylene glycol is printed in reverse image on one side of a translucent paper sheet. After printing, the ink is dried to evaporate a portion of the ethylene glycol so that the dried ink contains approximately 3.0% to 6.25% by weight of ethylene glycol. The polyamid resin is soluble in alcohol so that multiple copies can be printed from the master using conventional duplicating equipment, and as the ink does not contain oils and greases there is no tendency of the ink to bleed or smear so that the masters can be bound in booklet form without the need of separating tissue sheets.
