Laser printable, dry-erase substrates, along with their methods of formation and use, are provided. The laser printable, dry-erase substrate can include a base sheet defining a surface and a dry-erase coating on the surface of the base sheet. The dry-erase coating comprises a film-forming polymeric material (e.g., a polyacryl, a polymethacryl, a polyurethane-polyacryl mixture, a polyurethane-polymethacryl mixture, an urethane-acryl copolymer, or a mixture thereof) and a wetting agent (e.g., a nonionic surfactant that has a polyethylene oxide chain and an aromatic hydrocarbon lipophilic or hydrophobic group). The film-forming polymeric material melts and flows at a laser printing temperature so as to bond to toner ink.

A reusable notebook is used with heat-erasable ink. The reusable notebook includes a binding configured to hold a plurality of pages, at least one cover, and at least one ready indicator. The ready indicator is configured to indicate that at least one page in the notebook has reached at least a critical temperature. The critical temperature is a predetermined minimum temperature that is sufficient to erase thermochromic ink on the page(s). The indication occurs when the ready indicator is at a temperature equal to or above a predetermined minimum temperature referred to as the ready temperature. When the ready indicator is at or above the ready temperature, the critical temperature of the at least one page is reached.

A trophy includes a base and an award element on a top of the base. A dry erase element on the trophy is configured to be reusable with a dry erase marker for reusing the trophy. The dry erase element may be integrated into the trophy at the base or award element.

A reusable envelope has one or more spaces thereon where address, return labels and/or postage can be removably placed or permanently affixed such as for finite number of shipments using a permanently affixed postage area, for example. The reusable envelope also includes a resealable closure allowing the interior of the envelope to be closed and reopened multiple times for multiple uses (shipments, receiving) or optionally to use a finite number of times by exposing the permanent adhesive to the flat and mating surface depending on user preference.

An erasable, polymeric paged writing book for small children, with textured, flexible, bordered pages and an internal spine to spread the book flat. The pages have rounded corners. The book closes by hook-and-loop tab. The pages have a smaller profile than the covers, for resistance to wear and distortion. A fold-away pocket holds chalk and grease pencils. Optionally, a pleated storage compartment is on one of the covers. The pages have a smaller profile than the covers, for resistance to wear and distortion.

Disclosed is a coating composition suitable for coating onto a wall or other substrate to yield a dry-erase coating. The composition may be prepared by providing an aminoalkoxysilane, and in the substantial absence of water, reacting a portion of the aminoalkoxysilane with a carbonate and reacting a portion of the aminoalkoxysilane with an epoxy compound. These reactions will result in a coating composition that comprises a mixture of alkoxysilylamines and alkoxysilylcarbamates. The coating composition can also include an alkyl amine in an amount effective to catalytically deprotect alkoxy groups to yield silanol groups, facilitating fast crosslinking.

Building blocks for making structures comprising a number of translucent inflatable blocks, wherein each translucent inflatable block has six identical sides having an outer surface, an inner surface, and four vertices; a magnetic connection element configured to connected at least two inflatable blocks of the number of translucent blocks, wherein the magnetic connection element is located on the inner surface of each of the six identical sides, wherein the magnetic connection element includes four corners, wherein the four corners are equidistant to the four vertices; a proximity switch in communication with a lighting element located on the inner surface of each of the six identical sides, wherein the lighting element is configured to emit colored light when the proximity switch is activated, wherein the proximity switch is activated when the inflatable blocks are connected via their respective magnetic connection elements; and at least one valve for inflating or deflating the inflatable blocks.
