Abstract: The present invention provides a mono coating film type waterborne coating composition comprising halogen free polyolefin resin, acryl polyol, acryl emulsion, and a solvent. According to the present invention, adhesion to a polyolefin substrate is excellent, and physical/chemical properties may be maintained with a single coating film instead of the currently used dual coating films, by a halogen free waterborne composition with physical/chemical properties similar to or more excellent than the existing oil coating or halogen-containing coating composition. Since these effects may be sufficiently obtained with a single coating film, consumption of coating may be reduced about 30-40% compared to the existing method, and particularly, cost reduction may be expected through decrease in equipment required for dual coating film, energy for drying coating film, attractive force of coating, productivity increase, and the like.

Abstract: Embodiments of the invention relate to the determination of the colour of a colour sample from an image of the colour sample. In one embodiment a colour sample capture card is provided having printed thereon colour samples of known colour (for example, XYZ tri-stimulus values). An image of the test colour sample is then captured using domestically available equipment, such as a consumer digital camera or camera-equipped mobile telephone, the image also containing the colour sample capture card. In one embodiment the image is then transmitted to a remote colour determination service for colour sample colour determination. Regression analysis is then performed using the RGB colour samples in the image and known XYZ colours thereof to characterise the colour capture response of the image capture device. Having characterised the image capture device the XYZ colour of the unknown colour sample can be determined from the RGB colour thereof in the image.

Abstract: The invention relates to a method of manufacturing a composite product, wherein a plurality of elements are assembled by gluing them together under pressure, the method comprising applying glue to at least one surface of each element on which glue is to be applied, assembling the elements to a desired structure and subjecting the assembled elements to pressure in a press, which method further comprising controlling the amount of at least one component of the glue applied. However, if unexpected delays occur in the production line, there is a risk that the waiting time for the elements of a batch on which glue already have been applied will be too long and gluing thus defective. As defective gluing means both loss of production and waste of material it has been found advisable to keep a reasonable safety margin and apply more glue than in the ideal case will be necessary. On the other hand, in cases there are no unexpected delays, this practice leads to use of more glue than necessary.

Abstract: The invention relates to a method of manufacturing a composite product, wherein a plurality of elements are assembled by gluing them together under pressure with a glue comprising at least one first component and at least one second component, which method further comprises controlling the relation between the second and the first components of the glue applied. The press time is often a limiting factor for the production capacity of a plant and renders the production planning difficult. The press time is affected not by the temperature of the elements, but also a great extent by the relation between the components in the glue and can be significantly decreased by increasing the amount of hardener compared to the amount of resin. According to the invention, it has been found that this can be utilised for controlling the gluing in a way so the production can be planned more efficiently.
