Abstract: A process for the in-line, high speed manufacturing of magnetic products is disclosed. The process comprises the steps of printing onto a substrate, drying the ink print, making the appropriate cuts or scores on the substrate, applying a slurry of magnetizable material onto the substrate to create the magnet, drying the applied material, magnetizing the magnetic material and cutting and forming the substrate to the desired dimensions. Each of these steps may be performed in a single, in-line manufacturing operation running at high speeds.

Abstract: A piece of printed material has preprinted, hidden data and includes a structure which prevents premature or unauthorized revealing of the hidden lottery or gaming data. For example, an instant scratch-off lottery ticket according to the invention includes a substrate, an ink layer disposed on the substrate, the ink layer including hidden lottery data. An ink-receptive layer is provided between the ink layer and the substrate and includes a first security mechanism for preventing unauthorized detection of the hidden data. A second security mechanism is disposed between the ink-receptive layer and the substrate which further prevents unauthorized detection of the lottery data.

Abstract: A scratch-off game card includes first and second sections. The first section is provided with a first set of game data covered by a substantially opaque scratch-off material. The second section is provided with a second set of game data covered by a substantially transparent material. The second section is further provided with a substantially transparent coating for marking the second section by rubbing with an object. The markings so made are erasable by, for example, pencil eraser or the like material.

Abstract: A piece of printed material has preprinted, hidden data and includes a structure which prevents premature revealing of the hidden data. For example, an instant scratch-off lottery ticket according to the invention includes a substrate, an ink layer disposed on the substrate, the ink layer including hidden lottery data. An elemental-metal-free ink-receptive layer is provided between the ink layer and the substrate, whereby the metal-free layer prevents migration of ink from the ink layer through the substrate when the substrate has been contacted with a solvent.

Abstract: A scratch-off game piece which contains a fragrance which is released during the game play action. The game piece is constructed by application of layers of fragrance containing material and scratch-off material over a support layer of printed sheet material such that when the scratch-off material is removed by the player, the fragrance containing capsules are ruptured and fragrance is released.

Abstract: Disclosed is a process for making carboxylic acid-containing mono- and polyether polyol addition products by reacting maleic acid, fumaric acid, itaconic acid, or mixtures thereof with at least one polyhydroxy-containing mono- or polyether compound (e.g. a polyether diol or triol) in the presence of a peroxy-type free radical initiator. Also disclosed are the processes of making polyurethane prepolymers and aqueous polyurethane dispersions from these carboxylic acid-containing mono- and polyether polyol addition products and processes for using these dispersions in coatings, adhesives and other useful products.

Abstract: Polyurethane foam formulations containing halogenated phosphate ester additives are inhibited against scorching through the use of an effective amount of 4,4'-bis(.alpha., .alpha.-dimethylbenyl)diphenylamine.
