An incandescent illuminating device having an antifragility coating covering at least a substantial portion of the glass envelope, the antifragility coating comprising a mixture of a relatively clear, resilient heat-stable polymer capable of adhering to glass and a plurality of light-transmitting, impact-absorbing particles, which are preferably small, hollow, heat-stable, frangible microspheres. The particles, preferably hollow microspheres, constitute from about 20% to about 60% by volume of the cured antifragility coating and are essentially colorless, have a high degree of light transmissivity, and have a low density and a diameter less than about the thickness of the antifragility coating. The particles act as a sacrificial material to absorb an impact giving the coating antifragility properties.

A non-aqueous polymeric dispersion of an acrylic or methacrylic polymer in a non-aqueous continuous phase comprised of a mixture of organic liquids, one of which is an alcohol, when applied to a suitable substrate, dries to produce a matte or low gloss coating which can be converted to a glossy coating by heating.

Non-aqueous polymeric dispersion of alkyl methacrylate and alkyl

A secure property device utilizing radiant energy reflectors applied to a magnetic data member is provided in which the diffusivity of reflections from the reflectors is enhanced by means of a polymeric diffuser which is chemically and optically compatible with the reflectors and with the magnetic data member to which it is applied.

Secure property device

A secure property device utilizing radiant energy reflectors applied to a magnetic data member is provided in which the specularity of reflections from the reflectors is enhanced by means of a polymeric primer which is chemically and optically compatible with the reflectors and with the magnetic data member to which it is applied.

A non-aqueous polymeric dispersion of an acrylic or methacrylic polymer in a non-aqueous continuous phase having a hydrogen bonding index, .delta., greater than 10, a dipole moment, .mu., between 0.5 and 2.5 and a solubility parameter, .delta., less than 8 dries to produce a matte or low gloss coating.

Non-aqueous polymeric dispersion and matte coatings produced therefrom

A secure property document is provided which includes an optical data set defined by radiant energy modifying elements underlying a magnetic data member for reflecting infrared radiation therethrough. Preferably, the infrared reflectors are comprised of a plurality of thin metallic elements vapor deposited onto a magnetic tape during manufacture prior to hot stamping.

Secure property document and method of manufacture

A secure property document and system are provided which prevents the use of fraudulent credit cards and other documents. The documents each include optical and magnetic data sets. Each data set contains data elements having a spacial relationship to at least some of the data elements contained in the other data set. The system reads and processes the data to determine whether or not the spacial relationship corresponds to that recorded for the particular document. If the spacial relationship codes do not agree within predetermined limits, the document is rejected by the system, whereby the transaction may be refused or additional information requested from the document holder.
