The invention relates to glass articles suitable for use as writable erasable marker boards. More particularly, disclosed is a strengthened glass article suitable for use as a writable erasable marker boards, wherein the glass sheet exhibits an ion exchanged glass having a front surface and a back surface and exhibiting a thickness of less than 2.0 mm and having a depth of layer (DOL) greater than 20 microns and a surface compressive strength of at least 300 MPa. The strengthened glass article exhibits certain optical properties which render it particularly suitable for use as a writable erasable marker boards electronic including: (1) shadow parallax to thickness ratio of less than 1 measured at a 60 degree incident light angle and for an index of refraction n; and, (2) a haze of less than 50%. Further disclosed is a markerboard with improved magnetic force attributes; sufficient to hold weak magnets in place.

A magnetic erasable writable material for large format applications is disclosed, and includes a cast polyvinylchloride film with a mount surface opposite an etched receiver surface. Also incorporated is a transparent polyester film that has a marking side with a first predetermined hardness and an opposite seal side, laminated to the receiver surface. The marking side includes a clear superstrate that has a second predetermined hardness and applied to the marking side of the polyester film to lower its surface energy. The receiver surface is treated to have a surface energy adjusted to enable improved adherence of printed and preformed graphic elements, which are encapsulated when laminated between the PET film and receiver surface. The superstrate includes a perfluoropolyether, a polyurethane, an acrylated polyurethane, and/or an acrylate resin to harden the material.

Provided is an electronic board system including an electronic board which includes a sheet on which a pattern for determining position information is printed and a glass layer which is formed on the sheet and has a thickness of 0.1 mm to 3 mm, an electronic pen which senses the pattern and extracts position information on the electronic board from the sensed pattern, and an information processing apparatus which receives the position information from the electronic pen and controls a processing result according to the received position information to be output on the electronic board.

A writing board for mounting to a structure includes a main panel made from transparent material, the main panel having a front writing surface and a rear surface. There is at least one holding device formed in the rear surface for holding a background material. The front writing surface is flat and the entire background material is completely visible through the main panel.

A playboard includes a first ferromagnetic metal plate, a first coating on an outer side of the first ferromagnetic metal plate, a first polyolefin film adhered to the inner side of the first ferromagnetic metal plate, a layer of low density polyethylene on the first polyolefin film adhered to the inner side of the first ferromagnetic metal plate, a second polyolefin film adhered to the layer of low density polyethylene on the first polyolefin film adhered to the inner side of the first ferromagnetic metal plate. The playboard preferably has a mounting means to secure the playboard to a wall. For example, the mounting means may be double sided tape and/or a hook and loop fastener.

An inflatable swimming pool includes a floor and a number of walls defining a pool interior configured to receive water. A drawing board is integrally formed or otherwise coupled to the pool and includes a selectively inflatable frame configured to securely hold a drawing surface configured to enable a user of the pool to draw or write on the drawing board while playing in the pool. A drawing utensil may be provided with the drawing board such as a water soluble crayon. A water sprayer assembly may be integrally formed with or coupled to the pool and include a port connectable to a water source and configured to deliver water from the water source to a sprayer element configured to spray water into the pool.
